Some notable changes in this release include support for several -webkit- prefixes and WebKit-specific interfaces. These platform features are non-standard, vendor-specific, and quite prevalent.

Non-standard, incompatible CSS breaks websites for user agents designed around standards. When a browser that doesn’t support -webkit- prefixes (such as Firefox 48 and below) visits one of these sites, the web looks broken. This will be the case until those sites update their CSS. That’s why Firefox 49 includes the following changes to accommodate WebKit-specific content:

A. As a user, improved compatibility with sites that were designed for WebKit browsers only, especially on mobile.

As a developer, you might want to go back and add unprefixed equivalents to your -webkit-only CSS so we can remove these from the web platform one day in the future (theoretically). Pro Tip: Unprefixed properties always come last.

Q. Did you just break my site?

A. We hope not! But you can toggle this for testing with the following preference:

A. No, that’s unnecessary and inadvisable. Keep using web standards and keep testing in multiple browsers. If you must use -webkit- prefixes (and there are fewer reasons to do so than ever before), make sure they’re above the unprefixed property in your CSS.
